Run secure deals from request to payment — all in one app. With TONNA, businesses close deals faster and safer. Every step of the deal cycle — from the first request to final payment — is protected and transparent, so both sides can focus on results, not risk. How secure deals work in TONNA Buyer sends a request: Describe the job, attach requirements, and invite offers. Suppliers respond: Each supplier sends a price, timeline, and bank details. Buyer chooses the best offer: Compare terms and select the most attractive proposal. Buyer makes a protected deposit: Funds are locked in a special bank account and the deal officially starts. Supplier completes the work: Documents, photos, and videos are uploaded directly into the deal for full transparency. Buyer accepts the result: One tap on “Accept and Pay” confirms that the work is done. Automatic payout to Supplier: The deposit is instantly released from the bank account to the Supplier’s account. Why TONNA works for business Better, faster results: Suppliers are motivated to deliver top-quality work on time to unlock payment. If they need extra funding, they can request a loan or factoring right inside the app. Built-in trust and protection: The deal structure makes cheating or non-payment virtually impossible, so both sides can work calmly and confidently. Faster cash flow: As soon as the Buyer taps “Accept and Pay”, money is sent within minutes. The deal status updates instantly, and funds reach the Supplier’s account the same day. TONNA is the new standard for secure business deals.
